Zucchini Disease

Question

The stalks of my zucchini plants are turning pure white while the blossoms, leaves and stems look perfectly healthy. I would like to know what has caused this and if it will be fatal to the plants or if there is something I need to do to save them?

Answer 1

Don't think it's powdery mildew because it's usually on the leaves. Shouldn't be sunburn, everything else is ok. If it were mine, I'd take samples to the local agricultural extension office and see what they say. Good luck.
